AbstractThe Aphebian Ramah Group , located in the Hebron Fiord - Nachvak Fiord area of the Torngat Mountains , northern Labrador, is composed of l702 m (5582 ft . ) of elastic and carbonate sedimentary rocks and a single thin volcanic flow . In this report it is divided into six new formations that are named and defined . Two contrasting lithological sequences are present . The lower sequence, formed by the Rowsell Harbour and Reddick Bight formations , consists of thick multicoloured quartzites, sandstones and laminites that were chiefly deposited on a shallow marine shelf. The upper sequence is formed by monotonous shales and slates, the Nullataktok and Typhoon Peak formations , by the intervening predominantly dolomitic Warspite Formation, and by greywackes and slates of the uppermost unit, the Cameron Brook Formation . Type sections are designated for each formation .
